I just tested Zabbix 1.9.3 alpha and tried out the new "Low-level discovery" feature, but i can`t get it to work like (i think) it should. These are the steps i made:

1. Add a Host - linked to no Template
2. Add a Template - clear -> no items/triggers...
3. Add a "discovery rule" to the Template :
Name: Interfaces
key: snmp.discovery
Type: snmp v2
OID: ifDescr
4. Add a "item prototype" to the "discovery rule":
Desciption: ifInOctets.$1
OID: ifInOctets.

KEY: ifInOctets.["

"]

Now when i try to link my Host to this Template i get:

" Cannot find host interface on host "Test" for item key "". "

But when i create the same "discovery rule" in the host, it works like a charm.
